Being the warrior that he is, Shawn Marion doesn’t particularly like to sit out basketball games.

Especially a game that’s as big as the one the Dallas Mavericks play tonight at 7 at the AT%T Center against the San Antonio Spurs. But Marion will sit out tonight’s game with a left calf contusion, marking the fourth straight game he’s missed since suffering the injury during a Mar. 6 home game against the Houston Rockets.

“It’s real frustrating, but everybody’s been very supportive and I’m just trying to get myself right,’’ Marion said after this morning’s shoot around at the AT%T Center. “I’m here to support the team the best way I can and let’s keep it going.’’

The Mavs have won all three games they’ve played since Marion’s latest injury. However, the Spurs will be the Mavs’ toughest challenge since they lost their leading rebounder and top defender.
